' I lClaim. (o1.112 2s7) This invention relates to sewing machines andhas particular reference to apparatus and design for an attachmentwhereby the presser foot of the machine may be suspended at various.

heights above the feed dogs for performing such operations asembroidering, darning, or other work in which it is desirable to shiftthe material laterally during the stitching operation. The

, primary object of'the invention resides'in the provision of anattachment of this character which is flexible in use yet well securedto the sewing machine without interfering with the normal operation ofthe machine.

Another object of the invention resides in thev provision of a device ofthis character in which the adjustment of the height of the presser footis more easily made.

Still another object of the invention is in the provision of a device ofthis character which is simple and economical in its construction. w

' In attachments for adjusting the height of presser feet heretoforemade the constructions have been pendulum devices which swing from theupper portion of the sewing machine head and have slots at their lowerends for, engaging the presser foot lever or have been rigidly securedattachments having books at their lower ends for suspending the presserfoot levers, both of which interfere to some extent with the normalmanual operation of the presser foot lever. In the present invention theprovision of a slot which slidably engages the presser foot lever in thelower portion of the attachment makes possible the desired non-rigidsuspension and at the same time limits the pendulum movement of theattachment.

While the foregoing objects are paramount, other and lesserobjects willbecome manifest as the description proceeds taken in connection with theaccompanying drawing wherein:

- Figure 2 is an enlarged perspective view of the head I.

needle 5 between each stitch.

I latter'at various heights by reason. of the adjustment previouslydescribed, and yet allowing Continuing with a more detailed descriptionof thedrawing, the numeral I generally designates' a sewing machine headhaving a presser foot2 attached to a vertical presser foot bar 3, theupper end 4 of which extends through the In the normal operation of asewing machine, I the presser foot 2 engages the material at itsunderside in order that the feed dogs positioned thereunder mayuniformly space thestitching 10 and direct the same in a straight line.

However, in certain types of sewing it isolesir-able to stitch invarious directions, such as required 'in 'embroidering, patching,darning, quilting, and the like, and, in order to accom- 15 plishsuchwork, the presser foot 2 is partially raised to prevent pressure againstthe feeddogs, but is. retained low enough that the presser foot 2 willdisengage the material from the'machine 20 The attachment is comprisedof an upper memher I having achannel 3 formed in its lower portion and avertically arranged slot 9 in the face of the member, the same beingapproximately the. same length as the said channel. At the upper end ofthe member 1 there is a laterally projecting hook ll] which is designedto engage the upperend 4 of thepresser foot bar 3 for suspending thedevice on the machine head I,

A lower member ll of the attachment has a relatively narrow upperportion l2, as particularly illustrated in Figure 3, which is designedfor slidable engagement within the channel 8. A series of internallythreaded apertures l3 in the upper portion I 2 are provided forretaining a set screw M which passes through the slot 9 of the uppermember I for telescopically adjusting the height of the lower member Theselective use of the apertures makes possible a greater -or lesserextension of the device. 0

4 Within the lowe gportion 55 of the lower member llthere is arranged avertical and longitudinal slot l6 which is designedto slidably engagethe presser-foot lever 6 and suspend the free manual manipulation of thelever 6.

The lower end a of the slot It, the point which suspends the lever 6,terminates in a laterally projectinghandle H, which may be formedintegral with the lower member H, the purpose of which is to expeditethe adjustment between the upper and lower members 1 and H Manifestly,the structure herein shown and described is capable of considerablechanges and modifications from time to time by those skilled in the artand such changes and modifications as may be resorted to falling withinthe spirit and intent of the invention may also be considered as fallingwithin the scope of the appended claim.

What is claimed is:

A presser foot support for a sewing machine having a pair oflongitudinally and slidably ad- 10 justable upper and lower members andmeans
